IMPROVEMENT IN CAN-NOZZLES.

Specification forming part of Letters PatentNo. 172,0!0, dated January 11, 1876; application led October 1, 1875.

To all whom it may concern Be it known that I, L. BACON Foss,of Bos ton, in the State of Massachusetts, have invented an Improvement in Gap and Neck for Kerosene and other Cans, of which the following is a specification or nozzle has been formed with a sharp edge to cut into the cork and make its seat. This is injurious, and soon leads to the destruction of the cork.

within the interior of this seat, and shape it so that its sides press against the metal, and a part of its lower surface tits the conical seat.

The best way of forming the seat is by an indentation, V-shaped, spun on the neck ot' the can near the top, so that the metal projects inward and upward all round, and then turns and projects outward and upward. This gives a smooth inner edge to the seat, slightly rounded, as ,shown these A is the neck, and B is the cap. The

in the drawings.

cap has a vertical slot, b, on its back, and the neck has a staple, c, which passes through the slot in the cap, and unites: the two together by a hinge, which mist be so constructed and proportioned as to allow the front of the cap to clear the neck when lifted up. The slot must not be so long upward as to come When the cap is on upon the indentation employed to form the neck and the lower extension of the slot must be so arranged that the cap will bind on the sides of the neck below when shut, and the diameter at this point shall be greater than the diagonal from a point just below the staple to the upper opposite edge of the cone ofthe neck. The cork d tits the cap B tightly at the top, and tapers away from the sides of the cap, so that its end fits tightly the inside of seat a, while its sides are compressed upon the upper surface of said seat. The cork by this means is subject to but slight wear.

I claim- In combination with the flaringl upper end a of the neck A, and with the cap B, the conical cork d, attached to said cap, and arranged to tit within said flaring end, substantially as and for the purpose shown.
